简介
Spring cloud config 分为两部分 server client
- config-server 配置服务端，服务管理配置信息
- config-client 客户端，客户端调用server端暴露接口获取配置信息
config-server
创建config-server
首先创建config-server工程.
文件结构：
├── config-server.iml
├── pom.xml
└── src
├── main
│ ├── java
│ │ └── com
│ │ └── lkl
│ │ └── springcloud
│ │ └── config
│ │ └── server
│ │ └── Application.java
│ └── resources
│ ├── application.properties
│ └── bootstrap.properties
└── test
└── java
pom.xml内容：

创建启动类 Application.Java
package com.lkl.springcloud.config.server;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.cloud.config.server.EnableConfigServer;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.RestController;
/**
* Created by liaokailin on 16/4/28.
*/
@Configuration
@EnableAutoConfiguration
@RestController
@EnableConfigServer
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
其中 @EnableConfigServer为关键注解
在resources文件下创建application.properties
server.port=8888
- application:表示应用名称,在client中通过
spring.config.name配置 - profile:表示获取指定环境下配置，例如开发环境、测试环境、生产环境 默认值default，实际开发中可以是 dev、test、demo、production等
- label: git标签，默认值master
如果application名称为foo，则可以采用如下方式访问：
http://localhost:8888/foo/default
http://localhost:8888/foo/development
只要是按照上面的规则配置即可访问.
config-client
创建config-client
目录结构如下：

│ │ └── com
│ │ └── lkl
│ │ └── springcloud
│ │ └── config
│ │ └── client
│ │ └── Application.java
│ └── resources
│ └── bootstrap.yml
└── test
└── java

package com.lkl.springcloud.config.client;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* Created by liaokailin on 16/4/28.
*/
@SpringBootApplication
@RestController
public class Application {
@Value("${name:World!}")
String bar;
@RequestMapping("/")
String hello() {
return "Hello " + bar + "!";
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
创建bootstrap.properties文件，其内容如下：
spring.application.name: foo
spring.cloud.config.env:default
spring.cloud.config.label:master
spring.cloud.config.uri:http://localhost:8888其中 spring.application.name 为应用名称，spring.cloud.config.uri 配置config-server暴露的获取配置接口,其默认值为http://localhost:8888
第二三项配置在前面已经提到过，配置的都为默认值，因此bootstrap.properties只需要配置应用名即可.
运行config-client
访问 http://localhost 得到 `Hello liaokailin` 获取到git上的配置信息
访问 http://localhost/env 得到所有的配置信息，可以发现获取配置信息成功.
